A transformer monitoring apparatus based on non-electricity comprehensive characteristic information includes a transient oil pressure characteristic measuring module, a transient oil flow characteristic measuring module, a transient acceleration characteristic measuring module, a signal conditioning and acquiring module, and a digital processing and analyzing module; the transient oil pressure characteristic measuring module, the transient oil flow characteristic measuring module, and the transient acceleration characteristic measuring module are each connected to the signal conditioning and acquiring module, and the signal conditioning and acquiring module is connected to the digital processing and analyzing module. A transformer monitoring method based on non-electricity comprehensive characteristic information is also provided. The apparatus and method calculate an operating oil pressure, an operating oil flow, and an operating acceleration, which characterize a running state of the transformer, by comprehensively using information of a plurality of non-electricity transient characteristics in the transformer.
